David Zarzycki 55db26faf9 Partially unbreak the build ...

CfgTraits was reverted almost two weeks ago upstream but will presumably
come back. See: e025d09b216dc2239e1b502f4f277abb6fb4648a

The PPC MMA clang types were added nine days ago.

The stdlib is still crashing deep in LLVM:

```
swifterror value can only be loaded and stored from, or as a swifterror argument!
%swift.error** %2
  %7 = bitcast %swift.error** %2 to %swift.opaque*
in function $ss7DecoderP16unkeyedContainers015UnkeyedDecodingC0_pyKFTj
```

From a lldb session, the function in question:

```
define protected swiftcc void @"$ss7DecoderP16unkeyedContainers015UnkeyedDecodingC0_pyKFTj"(%Ts24UnkeyedDecodingContainerP* noalias nocapture sret %0, %swift.opaque* noalias nocapture swiftself %1, %swift.error** noalias nocapture swifterror dereferenceable(8) %2, %swift.type* %3, i8** %4) #0 {
  %6 = bitcast %Ts24UnkeyedDecodingContainerP* %0 to %swift.opaque*
  %7 = bitcast %swift.error** %2 to %swift.opaque*
  tail call swiftcc void @"$sSK5index6before5IndexQzAD_tFTj"(%swift.opaque* noalias nocapture sret %6, %swift.opaque* noalias nocapture %1, %swift.opaque* noalias nocapture swiftself %7, %swift.type* %3, i8** %4) #0
  ret void
}
```
